Description

Technical Field

[0001] The invention relates to a heating patch for skin beautification. Background Art

[0002] Generally speaking, a facial mask is a product that contains active substances or cosmetics, etc., so that when it is applied to the face or other skin, it can supply nutrition to the skin and make the skin elastic. The above-mentioned active substances contain various ingredients useful to the skin, such as moisturizers and whitening agents.

[0003] In order to enable the skin to absorb a large amount of active substances or cosmetics, such facial masks are made of non-woven fabrics. However, there is a problem that a satisfactory amount of skin absorption and efficacy cannot be obtained for the active ingredients contained in the facial mask through a simple absorption method.

[0004] In order to improve the above problems, conventional facial masks have improved the composition of active ingredients or cosmetics by applying various methods. However, such methods increase the manufacturing cost in terms of expenses, and there is a problem of reduced efficiency compared to the increased price.

[0005] As an alternative, a method of providing heat by a planar heating element has been proposed. However, since the conventional method is to simply attach the planar heating element to the outer body, when applied to a curved part of the body, there is a problem that it cannot completely adhere to the curved part of the body, and there is a limitation that it can only simply generate heat, but cannot generate heat at a uniform temperature.

[0014] Furthermore, the second pattern may be attached to one side of the first pattern by means of a conductive adhesive layer containing vertical conductive fillers.

[0015] Furthermore, the first electrode may be formed along an edge of the substrate portion, and the second electrode may be formed to be located inside the substrate portion.

[0016] Furthermore, the first electrode may include a first part and a second part that are physically separated from each other, so that power applied from the outside can be applied simultaneously through two paths. The first part and the second part may be formed on the substrate portion and arranged on both sides of the center line with a virtual center line as a reference.

[0017] Furthermore, a plurality of the heat generating parts may be arranged between the first electrode and the second electrode, and the plurality of heat generating parts may be connected in parallel with the applying electrode part.

[0018] Furthermore, the plurality of heat generating portions may be formed such that the total area of ​​the conductive heat generating material included in each heat generating portion is the same.

[0019] Furthermore, the plurality of heat generating portions may be formed such that the total lengths of the first heat generating electrode and the second heat generating electrode included in each heat generating portion are the same.

[0020] Also, the first electrode and the second electrode may be formed to have a width relatively wider than that of the first heat-generating electrode and the second heat-generating electrode.

DETAILED DESCRIPTION

[0037] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily implement the present invention. The present invention can be implemented in various forms and is not limited to the embodiments described herein. In order to clearly describe the present invention in the accompanying drawings, parts not related to the description are omitted, and the same or similar structural elements are given the same reference numerals throughout the specification.

[0038] When powered, the skin beauty heating patch 100 according to an embodiment of the present invention can generate heat in a state of being in close contact with the user's skin to achieve a warming function. Thus, the skin beauty heating patch 100 according to an embodiment of the present invention promotes the penetration of effective ingredients into the user's skin side, thereby enhancing the skin beauty effect.

[0039] Furthermore, the skin care heating patch 100 according to an embodiment of the present invention can help activate skin collagen by transferring heat to the user's skin, and can induce the discharge of unnecessary excrement by opening the pores.

[0040] In this case, the heating patch 100 for skin care according to one embodiment of the present invention can be realized in the shape of a mask that fits closely to the entire face, and can provide a warming function to a large area corresponding to the forehead, cheeks, chin and other areas of the face, and can make the heating part heat evenly regardless of the position.

[0041] In this case, the skin care heating patch 100 according to an embodiment of the present invention may include at least one opening 102 formed through, and the opening 102 may be formed at positions corresponding to the eyes and the mouth of the face when the face is in close contact with the face.

[0042] Furthermore, the skin care heating patch 100 according to an embodiment of the present invention may include at least one cutout portion 104. The cutout portion 104 may be formed at a position corresponding to the nose of the face when the cutout portion 104 is in close contact with the face.

[0043] Thus, the skin care heating patch 100 according to one embodiment of the present invention can accommodate the eyes and the mouth through the opening 102, so that one side can be completely in close contact with the face.

[0044] like Figure 1 As shown, the skin care heating patch 100 according to one embodiment of the present invention includes a substrate portion 110 , an applying electrode portion 120 , a heating portion 130 , and a cover member 140 .

[0045] The substrate unit 110 may be provided in a plate shape having a predetermined area, and may support the applying electrode unit 120 and the heating unit 130 formed on at least one surface.

[0046] As an example, the substrate 110 may have substantially the same shape as the cover member 140. Thus, the skin care heating patch 100 according to an embodiment of the present invention may have a planar shape such that the heating portion 130 has a large heating area through the substrate 110.

[0047] In this case, the substrate portion 110 may be flexible and stretchable.

[0048] To this end, the substrate portion 110 may be formed of a porous substrate having pores, and the applying electrode portion 120 and the heating portion 130 may be formed on at least one surface of the substrate portion 110 .

[0049] Therefore, the skin care heating patch 100 according to one embodiment of the present invention can be deformed freely, so that it can be completely attached to curved parts such as the face.

[0050] Furthermore, in the skin care heating patch 100 according to an embodiment of the present invention, the electrode applying part 120 and the heating part 130 may be formed by filling the pores with conductive paste, respectively. Thus, even if the substrate 110 is deformed by an external force, cracks may be prevented from being generated in the patterns constituting the electrode applying part 120 and the heating part 130.

[0051] Therefore, the substrate unit 110 may stably function as a circuit board for forming patterns of the applying electrode unit 120 and the heating unit 130 .

[0052] As an example, the porous substrate may be a cloth, fabric, nonwoven fabric, porous film, membrane, etc. having pores formed therein. However, the porous substrate is not limited to the above materials, and any material may be used without limitation as long as it has stretchability and flexibility and has pores of a predetermined size.

[0053] In this case, the pores 114 formed in the substrate 110 may have an appropriate size in consideration of the particle size of the conductive paste. This is because when the pore size is too small, the conductive paste particles may not penetrate or impregnate smoothly.

[0054] As a non-limiting example, Figure 5 As shown, the substrate portion 110 may be a nanofiber web formed such that nanofibers 112 including a synthetic polymer have pores 114 .

[0055] Therefore, in the skin beauty heating patch 100 according to one embodiment of the present invention, when the substrate portion 110 is formed by a nanofiber mesh, the substrate portion 110 can have significantly better warping properties than a polyimide film used as a conventional flexible circuit board, and can also have excellent restoring force that allows it to return to its original state even if folded or wrinkled.

[0056] In this case, the substrate 110 may be a single-layer or multi-layer nanofiber web, which is formed by electrospinning a spinning solution in which a synthetic polymer and a solvent are mixed to have pores 114. The solvent may be water or alcohol, or may be used alone or in a mixture with an organic solvent such as dimethylacetamide or acetone other than water or alcohol.

[0057] Furthermore, the synthetic polymer may be a fiber-forming polymer that has stretchability and flexibility and can be formed into a nanofiber web by electrospinning.

[0058] As a specific example, as the synthetic polymer, polyvinylidene fluoride (PVDF) can be used alone, but it can also be a mixture of a specified amount of polyvinylidene fluoride and polyurethane (PU, polyuet hersulfone) to ensure stretchability and soft touch. As an alternative, the synthetic polymer can be a mixture of a specified amount of polyvinylidene fluoride and polyether sulfone (PES, polyether sulfone) to ensure stretchability and heat resistance.

[0059] However, the synthetic polymer is not limited thereto, and any known material may be used as long as it can realize a nanofiber web by electrospinning and has flexibility and stretchability.

[0060] As described above, in the skin care heating patch 100 according to an embodiment of the present invention, the base plate 110 is formed of a porous base material having flexibility and stretchability, thereby ensuring flexibility and stretchability.

[0061] Therefore, even if the skin beauty heating patch 100 according to one embodiment of the present invention is attached to a curved part of the skin such as the face, it can adapt to the curved part by deformation, thereby increasing the adhesion with the skin, and the heat generated from the above-mentioned heating part 130 can be smoothly transferred to the skin side.

[0062] Furthermore, in the heating patch 100 for skin care according to one embodiment of the present invention, the pattern constituting the above-mentioned applying electrode portion 120 and the heating portion 130 is configured in the form of conductive paste particles filling the pores 114 formed in the substrate portion 110 together with the surface of the substrate portion 110, thereby significantly reducing the possibility of cracks occurring when deformed by external force.

[0063] At the same time, in the heating patch 100 for skin care according to one embodiment of the present invention, even if the substrate portion 110 is bent or wrinkled so that a portion of the pattern constituting the application electrode portion 120 and the heating portion 130 is broken, at least a portion of the pattern can be kept connected by the conductive paste filled in the pores 114, thereby significantly reducing the possibility of an electrical short circuit.

[0064] Furthermore, in the skin beauty heating patch 100 according to an embodiment of the present invention, the substrate portion 110 is formed of a porous substrate, and thus can have a very thin thickness, thereby making the overall thickness thinner. Thus, even if the skin beauty heating patch 100 according to an embodiment of the present invention is attached to the skin with the aid of cosmetics or ampoules, the possibility of the skin beauty heating patch 100 according to an embodiment of the present invention being separated from the user's skin can be significantly reduced.

[0065] like Figure 2 As shown, the applying electrode unit 120 may be formed in a predetermined pattern on at least one surface of the substrate unit 110 , and may form a path for providing power supplied from the outside to the heating unit 130 when power is applied.

[0066] As described above, the applying electrode unit 120 may be formed in a predetermined pattern on one surface of the substrate unit 110 , and may include a first electrode 121 and a second electrode 122 , so as to receive power supplied from the outside.

[0067] That is, the first electrode 121 and the second electrode 122 may be formed on one side of the substrate 110 in a state of being separated from each other so as to receive power supplied from the outside, and when power is applied, the first electrode 121 and the second electrode 122 may be energized to each other through the heating unit 130. In this case, the first electrode 121 may be a positive electrode, and the second electrode 122 may be a negative electrode.

[0068] Thus, when power is applied to the electrode applying unit 120 , current may flow along the first electrode 121 - the heating unit 130 - the second electrode 122 in sequence, and power may be supplied to the heating unit 130 .

[0069] In this case, the applying electrode part 120 may be in a strip shape so that power can be smoothly supplied to the heating part 130 even if the heating part 130 is formed at various positions of the substrate part 110 .

[0070] As an example, the first electrode 121 may be in a strip shape along the edge of the substrate portion 110 , the second electrode 122 may be in a strip shape to be located on the inner side of the substrate portion 110 , and the heating portion 130 may be formed to be located between the first electrode 121 and the second electrode 122 .

[0071] Furthermore, the applying electrode unit 120 may be configured such that power supplied from the outside is supplied simultaneously through two paths.

[0072] As an example, the first electrode 121 may include a first portion A and a second portion B that are physically separated from each other. The first portion A and the second portion B may be formed on the substrate 110 in a manner of being arranged on the left and right sides of a virtual center line based on the center line.

[0073] That is, the first portion A and the second portion B of the first electrode 121 may be connected in parallel to a power source supplied from the outside.

[0074] Therefore, when power is applied, compared with the case where the current flows along the first electrode 121-heating portion 130-second electrode 122, since the first electrode 121 is formed with one, the path of the current flowing along the first part A-heating portion 130-second electrode 122 or along the second part B-heating portion 130-second electrode 122 can be shortened, and the resistance of the first part A and the second part B themselves can be reduced.

[0075] Therefore, even if multiple heating parts 130 are connected in parallel between the first electrode 121 and the second electrode 122, the total power supply time supplied to each heating part 130 can be shortened, the response time of the heating part 130 can be shortened, and the size of the driving voltage required to make the above-mentioned heating part 130 generate heat can be reduced.

[0076] On the other hand, the applying electrode unit 120 may be formed in at least two layers. That is, the first electrode 121 and the second electrode 122 may include first patterns 121a and 122a directly formed on the substrate unit 110 and second patterns 122b and 122b stacked on one side of the first patterns 121a and 122a.

[0077] In this case, as described above, the first patterns 121a and 122a may be printed patterns formed by filling the pores 114 formed in the substrate portion 110 with conductive paste, and the second patterns 122b and 122b may be metal sheets having the same shape as the first patterns 121a and 122a.

[0078] That is, the first patterns 121a and 122a may be printed patterns formed on the substrate 110 by printing a conductive paste, and the conductive paste may completely or partially fill the pores 114 formed on the substrate 110 together with the surface of the substrate 110. The conductive paste may be Ag paste, but is not limited thereto, and any known conductive paste for forming an electrode may be applied.

[0079] Furthermore, the metal sheet may be copper foil or aluminum foil, and the second patterns 122b, 122b may be attached to one side of the first patterns 121a, 122a by means of a conductive adhesive layer.

[0080] Among them, the above-mentioned conductive adhesive layer can be an adhesive layer containing vertically conductive fillers such as Ni, and the above-mentioned second patterns 122b, 122b can be stamped bodies punched from metal sheets with a predetermined area, which have the same shape as the above-mentioned first patterns 121a, 122a.

[0081] Thus, the applying electrode unit 120 can be smoothly connected to the heating unit 130 formed on the substrate unit 110 through the first patterns 121a and 122a, and the resistance of the first electrode 121 and the second electrode 122 can be reduced through the second patterns 122b and 122b. Therefore, even if a plurality of heating units 130 are connected in parallel between the first electrode 121 and the second electrode 122, each heating unit 130 can generate heat uniformly.

[0082] This can be done through Figure 6 confirm.

[0083] That is, from Figure 6 Part (a) can confirm that when the first electrode 121 and the second electrode 122 are respectively composed of only the first patterns 121a and 122a, and a plurality of heating parts 130 are connected in parallel between the first electrode 121 and the second electrode 122, the average heating temperature of the plurality of heating parts 130 is 37.1°C, and the heating temperature of the heating part 130 that heats to the highest temperature among the plurality of heating parts 130 is 73.8°C.

[0084] On the contrary, from Figure 6Part (b) can confirm that when the first electrode 121 and the second electrode 122 are respectively composed of a stacked form including the first pattern 121a, 122a and the second pattern 122b, 122b, and a plurality of heating parts 130 are connected in parallel between the first electrode 121 and the second electrode 122, the average heating temperature of the plurality of heating parts 130 is 35.9°C, and the heating temperature of the heating part 130 that heats to the highest temperature among the plurality of heating parts 130 is 57.4°C.

[0085] Thus, it can be confirmed that there is no significant difference in the average heating temperature when the first electrode 121 and the second electrode 122 are respectively composed of only the first patterns 121a and 122a and when the first electrode 121 and the second electrode 122 are respectively composed of a stacked form including the first patterns 121a and 122a and the second patterns 122b and 122b.

[0086] However, it can be confirmed that when the first electrode 121 and the second electrode 122 are respectively composed of only the first patterns 121a and 122a, the heating temperature of the heating portion that heats to the highest temperature is more than 16°C higher than the heating temperature of the heating portion that heats to the highest temperature when the first electrode 121 and the second electrode 122 are respectively composed of a stacked form including the first patterns 121a and 122a and the second patterns 122b and 122b.

[0087] Thus, it can be confirmed that when the first electrode 121 and the second electrode 122 are respectively composed of only the first patterns 121a and 122a, the heating temperature deviation between the multiple heating parts 130 connected in parallel between the first electrode 121 and the second electrode 122 is large, but when they are composed of a stacked form including the first patterns 121a, 122a and the second patterns 122b, 122b, the heating temperature deviation of the multiple heating parts 130 connected in parallel between the first electrode 121 and the second electrode 122 is not large, and heat can be generated at a uniform temperature.

[0088] The heating unit 130 may be formed on one side of the substrate unit 110 to be electrically connected to the applying electrode unit 120. The heating unit 130 may generate heat when power is applied.

[0089] In this case, the heating unit 130 may include a first heating electrode 131 and a second heating electrode 132 which are not electrically connected to each other. When power is applied, the first heating electrode 131 and the second heating electrode 132 may be electrically connected to each other through a plurality of conductive heating materials 133 .

[0090] Specifically, Figures 2 to 4As shown, the first heating electrode 131 may be a linear pattern having a predetermined length and extending from the first electrode 121 to the second electrode 122 , and the second heating electrode 132 may be a linear pattern having a predetermined length and extending from the second electrode 122 to the first electrode 121 .

[0091] In this case, the first heat-generating electrode 131 and the second heat-generating electrode 132 can be respectively formed on the substrate portion 110 with a predetermined interval so that a portion of their lengths face each other, and the plurality of conductive heat-generating materials 133 can be formed on the substrate portion 110 to cover an overlapping portion formed by a portion of the lengths of the first heat-generating electrode 131 and the second heat-generating electrode 132 facing each other.

[0092] Therefore, one end of the first heat-generating electrode 131 and the second heat-generating electrode 132 may be connected to each other via the plurality of conductive heat-generating materials 133 while being connected to the first electrode 121 and the second electrode 122 .

[0093] In this case, the plurality of conductive heat-generating materials 133 may be formed on the substrate 110 such that overlapping portions with some lengths facing each other are spaced apart by a predetermined interval along the length direction of the first heat-generating electrode 131 and the second heat-generating electrode 132 .

[0094] In this case, when power is supplied, the plurality of conductive heat-generating materials 133 can make the first heat-generating electrode 131 and the second heat-generating electrode 132 electrically connected to each other and generate heat.

[0095] Therefore, when power is supplied to the heating unit 130 through the applying electrode unit 120 , the first heating electrode 131 and the second heating electrode 132 may be electrically connected to each other through the conductive heating material 133 , and the conductive heating material 133 may generate heat using the supplied power.

[0096] Thus, when power is supplied, the skin care heating patch 100 according to one embodiment of the present invention can achieve a warming function through the heat generated from the heating part 130 .

[0097] In this case, the first heating electrode 131 and the second heating electrode 132 may each be a linear pattern that is bent at least once. As an example, the first heating electrode 131 and the second heating electrode 132 may each be a shape that is bent at least once in the middle of the length. As an example, the first heating electrode 131 and the second heating electrode 132 may each have a linear pattern that is bent at least once in the middle of the length. shape, A shape among shapes and their combination shapes.

[0098] Therefore, in the skin care heating patch 100 according to an embodiment of the present invention, even if the plurality of conductive heating materials 133 are spaced apart along the length direction of the first heating electrode 131 and the second heating electrode 132 , the heating portion 130 can be implemented in a planar shape.

[0099] Thus, the skin care heating patch 100 according to an embodiment of the present invention can provide heat to corresponding parts of the face such as the forehead, cheeks and chin over a large area.

[0100] On the other hand, the conductive heating material 133 may be formed of a conductive constant temperature heating material so as to maintain a target temperature when power is supplied.

[0101] That is, the conductive constant temperature heat generating material may be a material capable of suppressing the heat generation temperature by increasing the resistance when the temperature rises.

[0102] As a non-limiting example, the conductive constant temperature heating material may be a known PTC material, and more specifically, may be a conductive carbon paste.

[0103] Therefore, in the heating unit 130, when power is supplied, if the heating temperature reaches the target temperature, the resistance of the conductive constant temperature heating material increases to prevent the current from flowing, thereby preventing the electrical connection between the first heating electrode 131 and the second heating electrode 132. Thus, the heating unit 130 can be prevented from heating to a temperature higher than the target temperature.

[0104] On the contrary, in the heating part 130, when the heating temperature drops below the target temperature, the resistance of the conductive constant temperature heating material decreases again to allow current to flow, thereby electrically connecting the first heating electrode 131 and the second heating electrode 132. Thus, the heating part 130 can be heated to the target temperature again by heating.

[0105] Therefore, in the skin care heating patch 100 according to an embodiment of the present invention, the heating portion 130 can always generate heat at a uniform temperature through the above process.

[0106] In the present invention, the heat generating portion 130 may be a printed pattern formed such that the conductive paste fills the pores 114 formed in the substrate portion 110 .

[0107] That is, the first heating electrode 131 and the second heating electrode 132 may be printed patterns formed on the substrate 110 by printing conductive paste, and the conductive paste may completely or partially fill the pores 114 formed on the substrate 110 together with the surface of the substrate 110. The conductive paste may be Ag paste, but is not limited thereto, and any known conductive paste for forming electrodes may be used.

[0108] Likewise, the conductive heat generating material 133 may be a printed pattern formed on the substrate 110 by printing, and the conductive heat generating material 133 may completely or partially fill the pores 114 formed on the substrate 110 together with the surface of the substrate 110 .

[0109] On the other hand, in the skin care heating patch 100 according to an embodiment of the present invention, a plurality of heating parts 130 may be provided. That is, in the skin care heating patch 100 according to an embodiment of the present invention, a plurality of heating parts 130 may be connected in parallel along the length direction of the applying electrode part 120.

[0110] Therefore, in the skin beauty heating patch 100 according to one embodiment of the present invention, even if each heating part 130 is in a planar shape, since the total length of each of the first heating electrode 131 and the second heating electrode 132 constituting each heating part 130 can be made very short, the self-resistance of each of the first heating electrode 131 and the second heating electrode 132 can be reduced, and the same voltage can be applied to each heating part 130.

[0111] Therefore, in the skin care heating patch 100 according to one embodiment of the present invention, even if a plurality of heating parts 130 are connected between the first electrode 121 and the second electrode 122, the magnitude of the driving voltage required to make each heating part 130 generate heat at the same target temperature can be reduced.

[0112] As an example, the multiple heating parts 130 can be connected in parallel with the applying electrode part 120 to be located at a position corresponding to at least one of the forehead, cheek and chin of the face, and can provide a warming function to a large area corresponding to at least one of the forehead, cheek and chin of the face.

[0113] In this case, in the skin care heating patch 100 according to one embodiment of the present invention, a plurality of heating parts 130 are provided, so that even if the first electrode 121 and the second electrode 122 are connected in parallel, the plurality of heating parts 130 can generate heat at the same temperature regardless of their formation positions.

[0114] Therefore, in the skin care heating patch 100 according to one embodiment of the present invention, heat can be uniformly transferred from each heating portion 130 to the skin side of the user.

[0115] To this end, the plurality of heat generating parts 130 may be formed such that the total area of ​​the plurality of conductive heat generating materials 133 included in each heat generating part 130 is the same. In this case, the plurality of conductive heat generating materials 133 included in one heat generating part 130 may be formed such that each area is the same.

[0116] Furthermore, the plurality of heating parts 130 may be formed such that the total length of the first heating electrode 131 and the second heating electrode 132 constituting each heating part 130 is the same, and the length of the overlapping region formed between the first heating electrode 131 and the second heating electrode 132 may be the same.

[0117] Among the plurality of heat generating units 130 , the distance between the first heat generating electrode 131 and the second heat generating electrode 132 facing each other in each heat generating unit 130 may be the same.

[0118] As a preferred embodiment, the plurality of conductive heating materials 133 constituting one heating portion 130 may be formed to have the same area, and the total number and total area of ​​the plurality of conductive heating materials 133 contained in each heating portion 130 may be the same. Furthermore, the first heating electrode 131 and the second heating electrode 132 constituting each heating portion 130 may be formed to have the same total length, and may be spaced apart by the same distance, and the length of the overlapping region formed between the first heating electrode 131 and the second heating electrode 132 may be the same.

[0119] Therefore, in the skin care heating patch 100 according to an embodiment of the present invention, the same voltage can be supplied from the applying electrode part 120 to each heating part 130 , and each heating part 130 can have the same self-resistance.

[0120] Therefore, in the skin care heating patch 100 according to an embodiment of the present invention, in addition to each heating portion 130 , each conductive heating material 133 included in each heating portion 130 can also generate heat with uniform temperature.

[0121] Therefore, in the skin care heating patch 100 according to one embodiment of the present invention, even if a plurality of heating parts 130 are used to realize a planar shape having a large heating area, each heating part 130 can generate heat of uniform temperature.

[0122] Therefore, in the heating patch 100 for skin care according to one embodiment of the present invention, even if it is realized as a planar heating element by a plurality of heating parts 130, the heating temperature of each heating part 130 can be kept uniform relative to the total area regardless of the overall shape and the formation position of each heating part 130.

[0123] On the other hand, the first electrode 121 and the second electrode 122 constituting the applying electrode unit 120 may be formed to have a relatively wider width than the first heat generating electrode 131 and the second heat generating electrode 132 constituting the heat generating unit 130 .

[0124] Thus, in the skin care heating patch 100 according to one embodiment of the present invention, each self-resistance of the first electrode 121 and the second electrode 122 can be relatively small compared to each self-resistance of the first heating electrode 131 and the second heating electrode 132. Thus, the power supplied from the outside can smoothly move to the heating part 130 side through the applying electrode part 120.

[0125] The pair of cover members 140 may be configured to surround the applying electrode unit 120 and the heating unit 130 formed on at least one side of the substrate unit 110. Thus, the pair of cover members 140 can prevent the applying electrode unit 120 and the heating unit 130 from being exposed to the outside. Furthermore, even if the skin beauty heating patch 100 according to an embodiment of the present invention is applied to a humid environment such as a facial mask or a functional substance applied to the user's body, the pair of cover members 140 can prevent liquid substances such as water from flowing into the side of the applying electrode unit 120 and the heating unit 130. Therefore, the skin beauty heating patch 100 according to an embodiment of the present invention can be stably driven even in a humid environment.

[0126] To this end, the pair of cover members 140 may be plate-shaped sheets having a predetermined area so as to cover the applying electrode unit 120 and the heat generating unit 130 .

[0127] This pair of cover parts 140 can be formed of materials such as polymer resins such as polyurethane (PU), polyethylene terephthalate (PET), polypropylene (PP), polyethylene (PE), polyvinylidene fluoride (PVDF), release paper, fabric, leather, etc., or can be formed of silicon material, or can be in the form of a molded product covered with a resin material formed by an insulator.

[0128] That is, the pair of cover parts 140 can be formed of a flexible and pliable material, and the pair of cover parts 140 can be formed of a flexible, scalable and moisture-proof material, so that the skin beauty heating patch 100 according to an embodiment of the present invention can be used in a humid environment.

[0129] As a specific example, Figure 2 As shown, the pair of cover members 140 may include a first cover member 141 and a second cover member 142 respectively disposed on both sides of the substrate portion 110 , and the first cover member 141 and the second cover member 142 may be attached via an adhesive layer or fixed by thermal welding.

[0130] The adhesive layer may be a liquid or gel inorganic material type, or a substrate type in which an adhesive material is coated on both sides of the substrate.

[0131] Furthermore, the first cover member 141 may be a cover member for covering a side of the substrate 110 on which the conductive heat generating material 133 is formed, and the second cover member 142 may be a cover member for covering a side of the substrate 110 on which the conductive heat generating material 133 is not formed.

[0132] In this case, one surface of the first cover member 141 may be a contact surface that comes into contact with the skin of the user.

[0133] Furthermore, the first cover member 141 and the second cover member 142 may have a transparent color, but may also be formed to have an opaque color such as black. In this case, the first cover member 141 and the second cover member 142 may have the same color or different colors.

[0134] In this case, the pair of cover members 140 may have flexibility and relatively greater hardness than the substrate 110 .

[0135] As an example, the pair of cover members 140 may be provided as thin film members and respectively attached to one surface of the substrate portion 110 .

[0136] Thus, even if the substrate 110 is formed of a porous substrate, the pair of cover members 140 can support one side of the substrate 110 to provide a supporting force for unfolding the substrate 110. Therefore, the pair of cover members 140 can supplement the strength of the substrate 110 while maintaining the substrate 110 in a plate shape.

[0137] On the other hand, the pair of cover members 140 may include an exposed portion 143, and the exposed portion 143 is cut so as to expose a portion of the applying electrode unit 120 to the outside. As an example, the exposed portion 143 may be formed on the pair of cover members 140 so as to expose the end of the first electrode 121 and the end of the second electrode 122 at the same time. Thus, the applying electrode unit 120 can be easily connected to an external power source through the exposed portion 143. In this case, terminals 123a and 123b having a predetermined length may be attached to the end of the first electrode 121 and the end of the second electrode 122 exposed to the outside through the exposed portion 143, respectively.

[0138] Although one embodiment of the present invention has been described above, the concept of the present invention is not limited to the embodiment presented in this specification, and ordinary technicians in the technical field of the present invention who understand the concept of the present invention can easily propose other embodiments within the scope of the same concept by adding, changing, deleting, adding structural elements, etc., but this will also fall within the scope of the present invention.
